Fabrication of Cd–Ba–S Nanoscale Structures on the Surface and in the Near-Surface Region of CdS Films by Implantation with Ba+ Ions

Cd 0.6 Ba 0.4 S nanostructures are obtained by the implantation of Ba + ions and subsequent annealing on the surface and in the surface region of CdS films. The parameters of the energy bands and the density of electronic states in the valence band are determined. With a decrease in the surface dime...

description Cd 0.6 Ba 0.4 S nanostructures are obtained by the implantation of Ba + ions and subsequent annealing on the surface and in the surface region of CdS films. The parameters of the energy bands and the density of electronic states in the valence band are determined. With a decrease in the surface dimensions of the nanocrystalline phases of Cd 0.6 Ba 0.4 S from 30 to 15 nm, the band gap E g is shown to increase from 2.3 to 2.6 eV. The band gap E g of the Cd 0.6 Ba 0.4 S nanofilms and nanolayers is 2.1 eV.
